IMPRovED LANTEvRN-GLOBE.

Specification forming part of Letters Patent No. 96,053, dated October 19, 1869.

.To a/ZZ whom, t may concern:

Be it known that I, MICHAEL SWEENEY, of Wheeling, in the county of Ohio and-State of Vest Virginia, have invented a new and useful Improvement in Lantern-Globes; and I do hereby declare that the following ,is a full,

.. clear, and exact description thereof, reference being had to the annexed drawings, making part of this specification, in which.-

Figure l is an elevation. Eig. 2 is a Vertical section. Figs. 3, 4, and 5 are transverse sections in different portions of the globe.

This invention relates to lanternglobes; and my improvement consists in constructing such globes with lenses or reflectors concavo-conveX in form and blown inthe globes While in process of formation, and so that the walls of the globes shall be of uniform thickness, or nearly so.

A in the drawings represents the seat, or that part of a lantern-globe which rests on the base of the lantern, from which part extends the body B, which terminates in the mouth C.,

ing taken to prepare the molds for this purpose in such a manner that the glass shall be made of uniform thickness, or as nearly so as possible, in all parts of the globe.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

As a new article of manufacture, a glass lantern-globe constructed with four (more or less) concave-convex reflectors, said reflectors being blown in the globe while being formed, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MICHAEL SWEENEY.
